RFE/RL Interview: Bolton On Iran, Ukraine, and Russia

U.S. national-security adviser John Bolton says that Iran cannot hope for sanctions relief without a "comprehensive deal," that Washington would be "happy" to join talks mediating between Ukraine and Russia, and that U.S. sanctions on Moscow are tougher than those imposed by the European Union. Bolton made the comments in an interview with RFE/RL's Olena Removska on August 27 in Kyiv.
